[英]How to export variable data to a JSON file on the server using JavaScript/PHP?
So let's say I have a HTML page and an input box on it. 假设我有一个HTML页面和一个输入框。 The user will type something in it, then I'll store it as a variable in JS, and then, can I somehow write the data of that variable to an already existing JSON file on the server?
用户将在其中键入一些内容,然后将其存储为JS中的变量,然后可以以某种方式将该变量的数据写入服务器上已经存在的JSON文件中吗?
How can I achieve this using JavaScript and/or PHP? 如何使用JavaScript和/或PHP实现此目的?
EDIT: I actually want to know how to write the data of a PHP variable to a JSON file that is in the same directory as the PHP file. 编辑:我实际上想知道如何将PHP变量的数据写入与PHP文件位于同一目录中的JSON文件。
file_put_contents("json_file.json",json_encode($array));Result:
{"key":"value","anotherkey":"anothervalue"}{“键”:“值”,“另一个键”:“另一个值”}
$array = json_decode(file_get_contents("json_file.json"),true);$ array = json_decode(file_get_contents(“ json_file.json”),true);\n$array['your_new_key'] = "your_new_value";
$ array ['your_new_key'] =“ your_new_value”;\nfile_put_contents("json_file.json",json_encode($array));
file_put_contents(“ json_file.json”,json_encode($ array));
